Ultion Locks Oxford High Security Cylinders Fitted

We fit Ultion locks in Oxford alongside other premium high security cylinders such as Avocet ABS, for £95 to £135 per door plus the cylinder at £50 to £120. These top tier ranges are generally rated both TS007 3-star and Sold Secure SS312 Diamond, and add features such as registered keys. In OX1 to OX4 we usually arrive within 10 to 30 minutes, and most single doors take under half an hour.

This page is about choosing between premium brands. If you just need to know whether your current lock is anti snap, see our general guide to anti snap locks in Oxford.

Ultion is a British brand of euro cylinder, sold mainly through locksmiths, that sits at the top end of the market. Its ranges are marketed as TS007 3-star and Sold Secure Diamond rated. Always check the markings on the cylinder itself, as specifications change between product lines.

• Attack response. Ultion describes its cylinders as designed so that a forced attack on the outside engages an internal lock, keeping the door secure. We do not go into how attacks work, only that the design aims to keep the door locked even if the front is damaged.
• Key registration. Keys are supplied with a card, and further copies are ordered against it rather than cut on the high street.
• Guarantee. Ultion has advertised a guarantee for owners whose cylinder is defeated by a break-in. The amount and conditions have changed over time, so read the current terms on the manufacturer’s website and register your lock if required.

A premium cylinder makes most sense where the door is at higher risk or the stakes of a key being copied are higher:

• After a break-in or attempted break-in. If a cylinder has already been attacked, many owners want the strongest replacement available. Our break-in make-safe service secures the door first.
• Ground floor flats. Doors opening onto communal hallways or rear courtyards in converted houses see little passing traffic.
• Insurers asking for a stated standard. Some policies, especially for high value contents, name Sold Secure Diamond or similar. Check your wording.
• Landlords with frequent tenant changes. Registered keys stop departing tenants copying keys at a kiosk. Our guide for Oxford landlords and letting agents covers changeover routines.
• Back doors and side gates out of view. The less visible the door, the more an extra layer earns its keep.

Each premium cylinder is measured on the door before ordering or fitting. On uPVC doors the sizes are usually close to standard, but on thicker slabs the offsets are longer, as explained on our composite door lock page. We check the multipoint strip engages cleanly at the same time, because a premium cylinder on a door that will not lock properly is money wasted.

You receive an itemised invoice naming the brand, range, rating and the door each cylinder was fitted to. That record is useful for insurers and for registering any manufacturer guarantee.
